Next Heracles was instructed to bring Eurystheus the mares of Diomedes. These horses dined on the flesh of travelers who made the mistake of accepting Diomedes' hospitality. In one version of the myth, Heracles pacified the beasts by feeding them their own master. In another, they satisfied their appetites on the hero's squire, a young man named Abderus. In any case, Heracles soon rounded them up and herded them down to sea, where he embarked them for Tiryns. Once he had shown them to Eurystheus, he released them. They were eventually eaten by wild animals on Mount Olympus.
